A force feedback mechanism designed for use with a mouse, trackball, keyboard, or other interface device manipulated by a user. The mechanism consists of a non-planar surface (11) that is substantially balanced with respect to a rotational axis "A". An actuator (12) controlled by a computer or microprocessor is connected to the non-planar surface (11). In response to signals from the computer or microprocessor the actuator (12) causes the non-planar surface (11) to rotate about its rotational axis "A", thus conveying force feedback to the user's thumb or fingertip.
